This paper shows an overview of biomechanical and physiological ef-fects of mechanical oscillations in humans. The biological function of mechanical oscillations is a complex pheno-menon that is analysed in various scientific fields. The basis of comple-xity is a large number of possible system states and solutions respec-tively which becomes obvious when one looks at the wide variety ofscientific results. Regarding the effects of vibrations on coordinationsome analyses show that direct vibration transfer to muscles or tendonscan lead to kinaesthetic illusions. Other studies found that low frequentwhole-body-vibration can reduce coordinative deficits in Parkinson’sdisease patients. The diversity of scientific data also becomes obvious inthe field of power and strength training. Results vary from slightly ne-gative to highly positive effects of vibrations stimuli.The physiological background of the wide variety of results is based onone hand on multiple physiological levels that can be affected by me-chanical oscillations and on the other hand on a non-linear structure ofinteraction between vibration stimuli and biological reaction.
